The triangle formed by RST is the same as the triangle formed by XYZ. If length RS is 13, YZ is 11, and XZ is 9, then RS = XY = 13. The answer is A.
Answer:
3x +11 =k
k -11 = 3x
x = (k -11) / 3
Step-by-step explanation:
They all can be split up to 6 groups because 12+18=30 so each group will have 5 kids in it.
20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200
14: 14, 28, 42, 56, 70, 84, 98, 112, 126, 140
140 is the smallest number they have in common.
